Zusammenfassung:PROBLEM TO BE SOLVED: To prevent a device involved in inspection of a tank and a pipe communicating with the tank, from being left non-detached after the inspection. SOLUTION: A piping joint provided for a tank includes: a lower connection port connected to the tank; a side connection port connected to a lateral pipe extending substantially horizontally; an upper opening by which the inside opens to the outside; a relay chamber for connecting a lower passage communicating with the lower connection port to a side passage communicating with the side connection port, and changing a passage direction; a lid member for closing the upper connection port; a stopper member for closing the lower passage; and a support post extending through the lid member with the leading end thereof integrated with the stopper member while keeping airtight. Furthermore, the lid member and stopper member are connected via the support post so as to be correlated with each other. COPYRIGHT: (C)2011,JPO&INPIT
